Rooftops and terraces with views
Downtown hotel roofs and Eixample attics open to the public at the price of a drink: the same city, seen from above, with a decorative pool. It's the plan that works best on the first night.
How they work
Some are open access with a drink and others ask for table reservation on weekends. Sunset is the golden hour: book ahead if you want a chair instead of standing.
Dress and moment
No evening wear required, but no flip-flops either: the code is relaxed-elegant. The perfect rooftop runs eight to eleven; after that, the party goes down to the street.
The cheap view
The free Bunkers del Carmel viewpoint with your own bottle and a blanket: same skyline, zero minimum spend, and the city's most celebrated sunset.
